2 Claims.

The present invention relates to improvements in containers especially adapted for receiving moth-repellent material, in the form of cakes, and pertains also to. improvements in-the cakes themselves.

Cakes of moth-repellentmaterial are, for purposes of transportation and storage, usually wrapped and properly sealed in sheet material impervious to air, for instance, cellophane. use, a cake, after having the wrapper removed therefrom, is placed into a suitably perforated container or box, to expose the moth-repellent substance to the action of air.

In the act of removing the wrapper from the cake, the hands of the user, obviously, com into contact with the moth-repellent material, whereby some of the moth-repellent adheres to the hands. Although the bulk of the repellent adhering to the hands is capable of being removed by washing and scrubbing, a thin film invariably stays on the hands and imparts a rather unpleasant odor to the same. This odor lingers until the said film has fully evaporated.

The primary object of the present invention is to so construct and arrange the container and cake that the moth-repellent substance is adapted to be exposed without necessitating contact between said substance and the hands of the user.

Another object of the invention is to provide a container of the type mentioned, which is very simple in construction, extremely efiicient in op eration, and which is capable of manufacture on a commercial scale or, in other words, one which is not so difficult to produce as to be beyond the reasonable cost of such an article.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

One of the many possible embodiments of the present invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of the improved container with the improved moth-repellent cake positioned therein; and I Figure 2 is a section taken on line 2-2 of Figure 1, on an enlarged scale.

The container comprises a body portion I I3 and a closure portion H. The body portion, consisting of a cylindrical wall l2 and a flat end I3, is made of a suitable stiff or rigid plastic material of a type that is resistant to corrosion or attack by the moth-repellent mass which is to be placed into the container. The closure portion is diskshaped and provided on its inner face'lfl with an annular flange l5, fitting tightly the mouth l6 of the container, the peripheral section ll of the closure being adapted to overlie the mouth-rim l8 of the container. The closure material, preferably, comprises the polymers of ethylene known under the trade-names Polithene and Polyethylenefl These are rubber-like thermoplastic compositions; have flexibility and elasticity; and are frictional. They are not corroded, nor attacked by the usually employed moth-repellent materials.

For the application of the closure to the body portion of the container, the flang of the former is placed over the mouth of the body portion and the closure pressed toward said body portion, whereby said flange is forced into the latter, the

closure being retained by friction on the container.

tainer. The flange being elastic, it is obvious. that the closure will adjust itself to slight varia-- tions in the size of the mouth of the body portion.

In the flat end 13 of th container body portion and in the closure disk are formed centrally disposed registering apertures 19 and 20, respectively.

The moth-repellent cake, denoted by the nu-- meral 2|, is disk-shaped to fit the container above described, and has formed therein a centrali hole 22, capable of coinciding with the apertures; in the two portions of the container. The cake is provided with a sealing wrapper 23, which is; impervious to air. Cellophane is especiallysuited for a wrapping material for the purposes of this invention.

Around its hole 20, the closure disk has formed on its inner face a 'bead 24, which serves to impart the desired strength to the closure in the region of its hole.

Means are provided for suspending the con- The suspending element herein disclosed is in the form of a hook 25, which may be attached to or made integral with the body portion II].

To place a cake into the container, the two elements of the latter are first taken apart. For

this purpose, the closure is grasped at a point of its peripheral section and easily and expeditiously peeled from the body portion of the container. The cake, enclosed .in its wrapper, is then placed into the body portion. Finally, the closure portion of the container is assembled with the body portion II] and the cake. In the assembled state, the apertures in the container are in alinement with the hole in the cake.

After the elements have thus'been assembled, the cake wrapper is ruptured by means of an instrument thrust through the registering apertures and hole in the container and cake,
